1、主要jar包：
httpclient-4.3.5.jar httpcore-4.3.2.jar
2、目录结构如图所示：
3、url.properties文件如下：
geturl=http://www.kuaidi100.com/query
posturl=http://www.tuling123.com/openapi/api
4、主要代码 GetAndPost.java：

5、读取配置文件中的url，PropertiesUtil.java：
package getandpost; import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties; public class PropertiesUtil {
public static Properties loadProperties(String... profilepath) throws IOException {
Properties prop = new Properties();
//传入的多个配置文件中，如有相同的属性名，以最后的配置文件属性值为准（会覆盖掉前面的属性值）
for (String path : profilepath) {
try {
prop.load(PropertiesUtil.class.getClassLoader().getResourceAsStream(path));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return prop;
}
}
运行结果：
